Salton Sea

The ghostly remains of an accidental sea 

Edit Place

This may sound obvious, but most rain eventually finds its way to the oceans, either via groundwater, rivers or lakes with permeable rock underneath. Some water, though, gets trapped in large basins that sit below sea level, and the water flows in but never flows out.

The Salton Sea near the Mexican border in Southern California has been at various levels for three million years. Technically a “saline lake,” it is saltier than the ocean, though slightly less salty than the Great Salt Lake. The basin was nearly dry until the beginning of the 1900s when failed irrigation canals diverted the Colorado River into the large basin, and the raging river brought the snowmelt from the Rockies into the Salton Sea.

The engineers from the Southern Pacific railroad were unable to stem the waterfall that the river created. By petitioning Congress and President Roosevelt, the engineers received the “battleship” loads of rock they needed to block the hole, however, it took more than six months before they diverted the river again. The Salton Sea had grown larger than Lake Tahoe to its current size of about 15 miles wide and 35 miles long.

At first, it was unclear that this lake was a nuisance. The Sea was a productive fishery during the 40s, and with post-war wealth became a popular tourist spot in the 50s with resorts, beach-front homes, and water skiing, seeing the likes of regulars like Sonny Bono and the Beach Boys.

But the incredible salinity of the lake and the heavy agriculture of Southern California slowly destroyed the ecosystem. Runoff from farms polluted the sea, and many of the fish species, save the hardy tilapia, could not survive, while migratory birds were poisoned with botulism and other lethal bacteria.

The State of California has been involved in efforts to restore the sea, but such extreme efforts are obviously easier said than done. The main worry is that the waters will eventually evaporate completely and turn the area into a giant dust bowl (more so than it already is) and blow toxic silt all the way to San Diego. The area is also home to one of the most diverse populations of birds in North America, housing over 400 species – which may also be lost with the sea. The state is hoping to build a series of levies and then flood small sections of the shoreline with fresh water to reduce the dust and to create a wetland habitat – the first small step in a long process of salvation. The local residents already suffer from asthma and other chronic ailments due to the dust – hopefully the state can help quell this from spreading further.

Currently the banks of the Salton Sea are vivid, surreal empty landscapes littered with dead fish and other detritus of human habitation.

Know Before You Go

No, it is right off of 86. Pretty easy to find. Be mindful of broken glass on the roads. Also, people still live out here. Don't yank open a door thinking it's a cool ghost house only to be staring down a shotgun.
